CLOCK-WINDING MECHANISM SPECIPICATION forming part of Letters Patent No.366,429, dated July 12, 1887.

Application filed June 2, I886.

To ctZZ whom/it may concern.-

Be it known that I, ABE RoBINsoN, of Brooklyn, in the county of Kingsand State of New York, have invented a new and Improved Olock-WVindingMechanism, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a new and improved automaticwinding mechanism for clocks actuated by springs.

ating a train of gear-wheels connected with the spring-barrel 0f theclock mechanism, and of an automatic wind-wheel-lock.ing device;

The invention also consists of various parts and details andcombinations of the same, as will be fully described hereinafter, andthen pointed out in the claims.

Reference is to be had to the accompanying. drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is an elevation of my improvement, parts being in section. Fig.2 is a bottom view of the same. Fig. 3is a rear View of the lockingdevice in its locked position. Fig. 4 is a similar view of the same inan unlocked posi tion. Fig. 5 is a crosssection of the same on theline00 a: of Fig. 4. Fig. 6 is a face View of the transmitting-wheel of thelocking device. Fig. 7 is asimilar view of the same from the other side.Fig. 8 is a central section on the line 11g of Fig.2. Fig. 9 is an innerface view of the transmitting wheel for the striking mechanism, and Fig.10 is an enlarged detail plan view of the locking device.

Awind-wheel, A, of any approved construction,is mounted in a frame, B,attached to the casing C, in which is mounted, in a suitable frame, D,an ordinary clock mechanism actuatcd by a coil-spring, one end of whichis at tached to the barrel E, the other end being attached to thespindle F, which forms a bearing for the barrel E, which operates theclock mechanism in the usual manner.

The casing O is preferably made in two parts, separated by a partition,0, so as to establish a flue, 0 from which the air or draft passesthrough the wind-wheel A and rotates the' same, and then the air passesinto the flue or 0 shaft connected with the rear end of the frame B ofthe wind-wheel A.

The wind-wheel A is mounted on a shaft,

The invention consists ofa wind-wheel actu- I Serial No. 203,920. (ModemA, which has its'bearing on the casing 13 and the partition 0, passingthrough thelatter and being provided on its inner end with a crankarm,G, which connects loosely with the arm H, attached to the spindle I,having its hearing on the swinging frame J, pivoted on a stud, J,attached to the plate J mounted on the'frame D, carrying the clockmechanism.

On the spindle I is secured a pinion, 1, which meshes into thegear-wheel I", attached to a spindle, 1 having its bearing in theswinging frame J, and the spindle l is provided with the pinion I, whichcan be thrown in and out of gear with the gear-wheel K, which is one ofa train of gear-wheels connected with the gear-wheel L, mounted on thespindle F, which forms a bearing for and is connected with thespring-barrel E. The gear-wheel L meshes into the gear-wheel M, securedto the spindle M, which carries loosely the gear- Whecl M, operating thestriking mechanism of the clock in the usual manner. To the gearwheel Mis attached one end of a spring, M", one end of which is secured to theratchetwheel M, also placed loosely on the spindle M and engaging apawl, M mounted on the frame D, carrying the clock mechanism. Theratchet-wheel M is fastened to the spindle M and engages aspring-pawl, Mpivoted on the ratchet-wheel M".

On the gear-wheel L is mounted a trans verse spindle, N, which carriesonone on one face of the wheel L, a cam, N, and, the other end,on theother face of the wheel L,carries a segmental gcarwvheel, N, whichengages with a stud, E, attached to thespringbarrel E, so that for everyrevolution of the wheel L the segmental gear-'wheel N is turned thedistance of one tooth and the cam N is turned the same distance.

On the cam N rests the collar O, placed loosely on' the spindle F, whichcollar is raised or lowered by the action of the turning of the cam N.On the collar 0 rests the free end of the spring O, secured to the plateJ and the free end of the spring is provided with the gages with theswinging frame J. 'To the latter is secured a spring-catch, Q, the freebent end of which engages a hook, 0 formed on the plate 0". A pin, 0,projects from the upper end of the plate 0", and is adapted to engagewith an arm, J secured to the swing ing frame J at its pivoting on thesaid stud J. The motion of the swinging frame J is limited by thestop-pin It, projecting from the plate J into a notch, J.

The lever S is pivoted to a stud, S, secured to the swinging frame J,projects through a slot in the partition O,and has its bearing in theplate S attached to the said partition 0. The outer spring end of thelever S is out of contact with the wind-wheelAwhen the clock is to bewound up, and is in contact with the wind-wheel A, and prevents theturning of the same after the clock is wound up.

The operation is as follows: WVhen the windwheel A is caused to rotateby the air passing up through the flue G the several parts of myimprovement are in the position shown in Figs. 1, 2, and 8--that is, theswinging frame J is so placed that its pinion I meshes into the gearwheel K of the train of gear wheels which rotates the gear-wheel K andthe pinion 1, deriving its own rotary motion from the wind-wheel A,whiehimparts a rotary motion to the spindle I by the crank-arm H, and thespindle transmits its rotary motion to the said pinion I, by means ofthe pinion I, meshing into the gear-wheel 1 mounted on the same shaft 1with the pinion 1. The train of gearwheels K imparts a rotary motion tothe gearwheel L in the direction of the arrow a, (see Fig. 3,) and themainspring, being attached by one end to the barrel E and by the otherend to the spindle F, carrying the wheel L, is wound up, the barrel Eremaining nearly stationary, only driving the clock mechanism, which isnot interfered with as long as the winding up lasts. The gear-wheel Lalso turns the gear-wheel M on the spindle M, but does not turn thegear-wheel M,which operates the striking mechanism as the pawl 1W glidesover the ratchet-wheel M, (which is also turned by the rotation of thespindle M,) and consequently does not move the gear-wheel M as long asthe winding up lasts.

For every revolution of the gear-wheel L the pin E',att aehed to thespring-barrel E, to rns the segmental gear-wheel N the distance of onetooth, and consequently turns the cam N the same distance, so that thecollar 0, resting on the cam N, is forced sidewise by the same, and whenthe mainspring is entirely wound upin the barrel E the collar 0 is inits uppermost position on the cam N and forces the free end of thespring 0' outward, which releases the spring Q, attached to the swingingframe J, from the notch 0", and the lever]? is moved in the direction ofthe arrow 1) by the inclined slotO", so that the spring P throws theswinging frame Jinto the position shown in Fig. 4, whereby the swingingframe J disengages the pinion I from the gear-wheel K of the train ofgear-wheels connected with the gear-wheel L. The arm J then rests on thelug O, and prevents the voluntary return of the swinging frame J.Thissudden movementof thesw1nging frame J forces the arm S to move inthe direction of the arrow 0, the plate S being fulcrumed, so that thespring end of the arm S engages with the wind-wheel A and pre vents itsfurther rotation. The mainspring, attached to the barrel E and thespindle F, causes the latter to rotate in the inverse direction of thearrow a, as soon as the said spring is wound up, as above stated, andthe wheel L is then also rotated in the same direction with the spindleF, and thereby reverses the motion of the segmental gear-wheel Nand thecam N, so that the collar 0 and the free end 0" of the spring 0 aregradually drawn inward until the cam is in its innermost position whenthe mainspring is nearly unwound. Then the lug 0, moving inward with thefree end of the spring 0, releases the arm J and the inclined slot 0,and the free end 0' ofthe spring 0 forces the lover I? back to itsformer position, so that the spring arm l throws the swinging frame J toits former position, (shown in Fig. 3,) whereby the lever S disengagesthe wind-wheel A, and thereby the latter is free to rotate, and thepinion I again meshes into the gear-wheel K of the train of gear-wheelswhich imparts motion to the gear-wheel L and the spindle F in thedirection of the arrow a, and the winding of the mainspring againcommences, as above described. The springQengages with the notch 0 andholds the swing ing frame J in a locked position. \Vhen the mainspringis unwound, the wheel L operates on the gear-wheel M" by means of thegearwheel M, turning the spindle M, which rotates the ratchet-wheel M,and as the pawl M is now in active engagement it turns the ratchet-wheelM", to which the pawl M is pivoted, and first compresses the spring M toits limit, and then turns the gear-wheel M, which operates the strikingmechanism.

It will be seen that when the motion of the gear-wheel L is reversed, soas to wind up the mainspring, the compressed spring M" keeps thegear-wheel M" in motion until the mainspring in the barrel E is wound upagain, as the pawl M holds the ratchet-wheel M" in position, so as topermit the spring M to act on the gear-wheel M and, consequently, on thestriking mechanism, which is not interfered with whether the mainspringis wound up or unwound.

The movement of the swinging frame Jmay be utilized in many ways to lockor unlock the wind-wheel A as, for instance, a double door attached tothe frame 13 could be opened or closed by the movement of the swingingframe J, which opening and closing of the door would cause a stopping orrunning of the wind-wheel.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1.
